I'm fairly ignorant on the matter. I was thinking of dabbling into some more hardcore audio, and maybe even entering a competition or two. I have 3 Infinity Perfect 12.1's, and was curious as to how you guys would power them if you were to compete in either SQ or SPL. Give me both sides of the spectrum. How are Infinity Amps? I was thinking of a Kappa 202a for each sub (?).
